 NOW THEREFORE, in consideration of the mutual covenants and conditions set forth herein,
the sufficiency of which is hereby acknowledged, the parties hereby agree as follows: 
 SECTION 1. LOAN REDUCTION;
ACKNOWLEDGEMENT 
 (a) The Company and the MHR Funds hereby agree that immediately and automatically upon the First Commercial Sale
(as such term is defined in the GLP-1 License Agreement) of a Licensed Product (as such term is defined it the GLP-1 License Agreement) in the United States or the European Union (including the United Kingdom even if the United Kingdom subsequently
ceases to be part of the European Union) that would result in any payment to the MHR Funds of any royalty pursuant to Section 1.a, 1.b or 1.c of Amendment No. 4: 

(i) the outstanding principal amount of the Loans (as defined in the Loan Agreement) pursuant to the Loan Agreement shall be
automatically and irrevocably reduced by an amount equal to $7,000,000 (the “Loan Reduction Amount”), which Loan Reduction Amount may be allocated among the Lenders (as such term is defined in the Loan Agreement) as determined by
the MHR Representative (as such term is defined in the Loan Agreement) in its sole discretion, and 
 (ii) the MHR Funds each
agree to irrevocably, absolutely and unconditionally waive any claims against the Company arising in relation to the Loan Reduction Amount and agree to forgive, cancel and discharge the Company from the obligation to repay the Loan Reduction Amount.

 (b) Except as specifically provided in Section 1(a) hereof, each of the Company and the MHR Funds irrevocably and unconditionally
acknowledge and agree that the Loan Agreement and the underlying financial obligations of the Company under the Loan Agreement remain in full force and effect. 

(c) Each of the Company and the MHR Funds acknowledge and agree that any direct or indirect sale, lease, conveyance or other disposition
(other than to any Subsidiary of the Company, and assuming a fair market value of at least $50,000) of all or any portion of the Company’s business or assets relating to Designated Products (as such term is defined in the Royalty Agreement),
shall constitute an “Asset Sale” as such term is defined in the Loan Agreement and Convertible Notes, for which the consent of the MHR Funds is required pursuant to Section 7(l) of the Loan Agreement and Convertible Notes,
respectively. 
 SECTION 2. RIGHTS OF THE MHR FUNDS UNDER THE NOVO NORDISK LICENSE AGREEMENTS 

(a) Royalty Assignment. If the GLP-1 License Agreement is terminated by Novo Nordisk (x) at any time prior to the First Commercial
Sale, (y) at any time within thirty (30) months after the First Commercial Sale (such period, the “Marketing Period”) or (z) at any time after the Marketing Period, if there shall have been within one (1) year
prior to such termination date (I) a failure to obtain or maintain any Regulatory Approval (as such term is defined in the GLP-1 License Agreement) or (II) any adverse safety or efficacy issues arising in connection with the use of a Licensed
Product prior to the termination date that results (whether 

  
 2 








 
prior to, on or following the termination date) in either the withdrawal of such Licensed Product from the market or in any action by any Regulatory Authority relating to the License Product,
including any action to require any change in the labelling requirements applicable to the Licensed Product, then: 
 (i) the
MHR Funds shall have a right to receive, and the Company shall pay in accordance with this Section 2(a)(i), a royalty of 0.5% on the net sales (but not, for the avoidance of doubt, in respect of any milestone payments) by Novo Nordisk or any of
its Affiliates of any single product (including all dosage forms and line extensions thereof) incorporating any of the Company’s proprietary delivery agents for which royalties on net sales are payable (the “Assigned Royalty”)
under any (a) Novo Nordisk License Agreement or (b) development and license agreement or similar agreement relating to the development or license of any products containing or utilizing the Company’s proprietary delivery agents for
oral administration entered into between the Company and Novo Nordisk or any of their respective Subsidiaries or Affiliates after the date hereof (a “Future License Agreement”), in accordance with the Royalty Assignment Election
made by MHR pursuant to Section 2(a)(ii) below; 
 (ii) The MHR Funds shall, from time to time and at any time, in their
sole and absolute discretion, elect which single product under any Novo Nordisk License Agreement or Future License Agreement to which the Assigned Royalty should apply (such election, the “Royalty Assignment Election”). Once the
MHR Funds make a Royalty Assignment Election and receive royalties hereunder with respect thereto, such Royalty Assignment Election shall become irrevocable; 

(iii) Any royalty due to the MHR Funds pursuant to this Agreement shall only be paid out of funds actually received by the
Company or any of its Subsidiaries from Novo Nordisk or any of its Affiliates under the applicable Novo Nordisk License Agreement or Future License Agreement. Within two (2) Business Days following the Company’s or any of its
Subsidiary’s receipt of any royalties under the agreement to which the Royalty Assignment Election applies in respect of net sales by Novo Nordisk or any of its Affiliates, the Company shall pay to the MHR Funds the Assigned Royalty in United
States dollars by bank wire transfer in immediately available funds to such bank account as shall be designated in writing by the MHR Funds from time to time; and 

(iv) The Company shall keep complete and accurate records in sufficient detail to enable the amounts payable pursuant to the
Assigned Royalty to be determined. Upon request of the MHR Funds, the Company shall permit an independent certified accounting firm of nationally recognized standing selected by the MHR Funds and reasonably acceptable to the Company, to have access
during normal business hours to such records of the Company as may be reasonably necessary to verify the accuracy of the royalty reports of the Company. The review by such accounting firm shall be conducted in confidence, provided that a summary of
the results of such review may be shared with the MHR Funds and the Company, who shall also keep such summary in confidence, except as required by applicable law. If such accounting firm concludes that additional amounts were owed to the MHR Funds
pursuant to the Assigned Royalty, the 

  
 3 








 
Company shall pay such additional amounts within two (2) Business Days of the date the MHR Funds deliver to the Company such accounting firm’s written report so concluding. The fees
charged by such accounting firm shall be paid by the MHR Funds unless such report identifies additional amounts of at least 5% of the total amounts payable hereunder in any calendar year owing under the Assigned Royalty, in which case the Company
shall pay all such fees. Promptly upon the entry by the Company into any Future License Agreement, or any amendment to any of the Novo Nordisk License Agreements, the Company shall provide a copy of such agreement or amendment to the MHR Funds. 

(b) Audit Rights. Upon the request of the MHR Funds, the Company will promptly (x) exercise any of its rights or options to
conduct any audits or similar reviews or examinations granted pursuant to any of the Novo Nordisk License Agreements or any Future License Agreement and (y) share the results of such audit or similar review or examination with the MHR Funds.

 SECTION 3. ADDITIONAL COVENANTS  

(a) MHR Protective Provisions. At any time when any Novo Nordisk License Agreement or any Future License Agreement is in effect, the
Company shall not, and shall cause its Subsidiaries not to, either directly or indirectly, do, or agree to do, any of the following without the prior written consent of the MHR Funds, and any such act or transaction entered into without such prior
written consent shall be null and void ab initio, and of no force or effect: 
 (i) enter into any Future License Agreement;

 (ii) terminate any Novo Nordisk License Agreement or any Future License Agreement; 

(iii) amend or modify any Novo Nordisk License Agreement or any Future License Agreement in any material respect, provided that
any such amendment or modification that in any manner could reasonably be expected to adversely affect any potential benefit to the MHR Funds under any of the rights granted to any of the MHR Funds pursuant to this Agreement shall be deemed to be
material for purposes of this Section 3(a)(iii); 
 (iv) assign or waive any of the Company’s rights under any Novo
Nordisk License Agreement or any Future License Agreement; 
 (v) accept payment from Novo Nordisk pursuant to any Novo
Nordisk License Agreement or any Future License Agreement in any form other than cash; 
 (vi) exercise any audit rights set
forth in any Novo Nordisk License Agreement or in any Future License Agreement, including pursuant to Section 7.6 of the Novo Nordisk License Agreements, without providing the MHR Funds with at least thirty (30) days prior written notice;

 (vii) sell, lease convey, assign, encumber or otherwise dispose, whether pursuant to a merger, consolidation or otherwise,
of any intellectual property owned or 

  
 4 








 
controlled by the Company or any of its Subsidiaries that is either licensed to Novo Nordisk or any of its Affiliates pursuant to any Novo Nordisk License Agreement or any Future License
Agreement or to which Novo Nordisk or any of its Affiliates has an option to license (whether on an exclusive or non-exclusive basis); or 

(viii) by operation of law or otherwise, merge or consolidate with Novo Nordisk or any of its Affiliates, or sell, transfer or
lease or otherwise dispose of all or any substantial part of its assets to Novo Nordisk or any of its Affiliates. 
 (b) Due
Performance. The Company and its Subsidiaries shall perform and comply in all respects with all obligations and covenants required by each of the Novo Nordisk License Agreements and any Future License Agreement to be performed or complied with
by the Company and its Subsidiaries.

Agreements or any Future License Agreements and provide a detailed description of all material terms relating thereto, including, without limitation, (A) the exercise by Novo Nordisk of any option, or the conversion of a Non-Exclusive Option

Agreement) as a Non-Exclusive Program Carrier (as defined in the Expansion Agreement) pursuant to the Expansion Agreement, in all cases within two (2) Business Days of such exercise. 

(ii) The Company shall promptly, but in any event no more than two (2) Business Days following the date of delivery to, or
receipt from, Novo Nordisk, provide to the MHR Funds a copy of all notifications and reports furnished to it from, or provided to, Novo Nordisk pursuant to any of the Novo Nordisk License Agreements or any Future License Agreements. 

(iii) The Company shall promptly, but in any event no more than two (2) Business Days after the Company has knowledge
thereof, notify the MHR Funds of any material breach of any of its obligations or covenants under any Novo Nordisk License Agreement or any Future License Agreements, and each other event or circumstance that has or could reasonably be expected to
result in the Company’s inability to perform any of its obligations or agreements under any Novo Nordisk License Agreement or any Future License Agreements, together with a detailed description of such material breach, event or circumstance,
and all actions taken or proposed to be taken in response thereto (any such notice, a “Default Notice”). Upon receipt of any Default Notice, the MHR Funds shall be entitled to take any and all actions reasonably intended to cure any
material breach that occurred, or prevent any material breach that may occur as a result of any event or circumstance identified in any Default Notice. 

  
 5 








 (d) Fees and Expenses. The Company shall pay, promptly, but in no event more than two
